BEAM ADJUSTER.

Application filed December 13, 1926. Serial Ho. 154,470.

This invention relates to so-called beam adjusters, a mechanism that isemployed in the pumping of Wells, said mechanism being used forconnecting an operating member,

13 such, as awalking-beam, to the clamp that holds the polish rod of thepump.

An object of the invention is to permit of displacement of the beamadjuster stem from the walking-beam or other operating memw ber,.while,at the same time, insuring against complete disconnection between theoperating member and said stem.

Another object is to improve the construction for mounting the stem onthe operating 35 member.

Further objects and advantages will appear in the subjoining detaileddescription. The accompanying drawings illustrate the invention:

Fig. 1 is a perspective view of a beam adjuster, constructed inaccordance with the provisions of this invention, a fragment of theoperating member, with which the beam adjuster is associated, beingshown in broken 35 lines. M

Fig. 2 is a perspective view of the saddle with the locking pin inplace.

Fig. 3 is a perspective view of the stem.

Fig. 4 is a perspective view of the bottom plate.

There is provided a saddle comprising a flat plate 5 and'upturnedflanges 6 along one of the longitudinal edges of the plate. At itsopposite ends the plate 5 is provided with longitudinal extending slots7, the pur ose of which will be mentioned hereina er. From the underfaceof the plate 5 projects spurs 8 adapted to penetrate the upper face ofthe operating member, a fragment of which is indicated at Ain Fig. 1.

The plate is provided with an opening 9 and the flanges 6 are onopposite sides of said opening. Projecting from the outer faces of theflanges 6 are ears l0 and 11 through which projects a pin 12, said pinserving to close the outer end of the opening 9. The pin 12 has a head13 at one end adapted to engage the car 10 and said pin has near itsother end a shoulder 14 adapted,

when the pin is turned to the position shown in Fig. 1, to engage theear -11 so as to prevent disengagement of the pin fromv the ear 7 pin'12is turned to the position shown in Fig. 2 and then moved endwise towardthe car 10. The shoulder 14 will prevent withdrawal of the in 12 fromthe car 10.

Seated on t e upper face of the plate 5 are flanges 17 that projectlaterally from a stem 18 and projecting up from sald flanges is an eye19 which may be engaged b a hoisting tackle when it is desired to dispace the stem from or replace the stem on the operating member A. Thestem 18 is adapted to extend through a vertical slot B in the end of theoperating member, in a manner well understood in this art, and theflanges 6 prevent sliding of the flanges 17 01f of the plate 5. I v

The. lower'end ofthe stem 18 may be con structed in any suitable mannerfor'yconnection with the polish rod clamp, not shown.-

18 has spaced furcations 20 through which extends a pin 21 held in placeby a head 22 at one end and a removable cotter pin 23 near its oppositeend. The means for connecting the pin 21 with the polish rod clamp, notshown, may be of any suitable construction and is not illustrated nordescribed in this specification as it constitutes'no portion of thepresent invention.

There is provided on the under-surface of the operating member A, abottom plate 24 having at its outer longitudinal edge a flange 25,which, in this particular instance, projects downwardly. The plate 24 isprovided near its opposite ends'wlth longitudinal extending slots 26through which project spurs 27 of hook shaped members 28 which extendvertically along the side faces of the operating member A and have theirupper ends enscrew threaded onto their upper. ends nuts 29 whichlieabove the plate 5. In thisinstance, washers 30 are interposed betweenthe nuts 29 and the late 5. It will be apparent from Fig. 1 t at thespurs 27 are driven into the underface of the operating member A. p

,In this instance the lower end of the stem gaged in the slots 7. Themembers 28 have In assembling the beam adjuster on the operating member,it is desirable to so position it that the stem 18 will hang vertically,and be in axial alignment with the polish rod of the pump whenthe-operating member is substantially .in horizontal position.Accordingly, in mountin the beam connecter on the operating mem er, theplate 5 will first be placed in position on the upper face of the ocrating member and then the stem 18 will place d in'position andconnected with the polish rod clamp in a manner well understood in thisart. If, after thus connecting the stem 18, said stem should not hangvertically when the operating member is substantially horizontal, theplate 5 will be moved lengthwise of the operating member until verticalhanging of the stem 18 is obtained. If the plate has-been correctlypositioned, the bottom plate 24 will be placed in position against theunderface of the operating member and the hookshaped members 28 willthen be assembled in position as shown in Fig. 1 and the nuts 29 tihtened. In ositioning the plate 2 1, care will be taken to have theflange 25 engage the stem 18 when the operating member is substantiallyhorizontal so that, when the operating member is swinging on the upperhalf of its up-.

stroke, the stem 18 will be held against swinging inwardly toward thefulcrum point of the o crating member, thus avoiding any apprecia 1ebending of the polish rod. On

-. the lower half of the downstroke of the stances, the stem'18 will beprevented from disen the opemng' 9 in the late 5 b the pid l i i It isto be noted that the innei faces of the flanges 6 extend aslant downward and inwardly so that, in event of the flanges 17 being unseatedfrom the plate 5 by a quicker descent-of the 0 rating memher than thestem 18, upon e nextsubseuentupstroke of the operatmg' member theflenges lf will be properly gui ed'into position on the plate 5 by theflanges 6;
